PETSCSPACESUM

"sum" - A PetscSpace object that encapsulates a sum of subspaces. That sum can either be direct or concatenate a concatenation.For example if A and B are spaces each with 2 components, the direct sum of A and B will also have 2 components while the concatenated sum will have 4 components.In both cases A and B must be defined over the same number of variables.
